Unicode contains a lot of great and useful things. And as things tend to go, people find creative uses for
them. It’s currently trendy to use some of Unicode’s special characters for “font effects”,
𝕝𝕚𝕜𝕖 𝕥𝕙𝕚𝕤 𝕖𝕩𝕒𝕞𝕡𝕝𝕖
(assuming you have good font support, you should see cool double struck letters reading “like this
example”). There are easy converters available for finding out the best
I was doing some Node.js V8 profiling work at the office near the end of the day and noticed my profile processing was taking a long time.
I figured it is just processor intensive and left it running for the day while I went home. To my surprise, the next day it was
still running! htop showed me it had accumulated 12 hours of CPU time and was still not finished. This led me to track down
a related issue and how to fix it.
I was wondering today how to filter uWSGI logs based on the request path because we had an endpoint that was filling our
logs with meaningless information. At least for me this was surprisingly difficult to find. So
here is an example command line option:
The log-filter flag takes in a regular expression that is used to include lines that match the
filter (so it works as a whitelist). To filter lines that don’t contain something, you can use
a negative lookahead.
So it turns out mechanical keyboards are like a drug to me. After I tried my first one at work, I
had toget more.
At the same time I started to pay attention to the ergonomics of my typing. I noticed that when I
typed a lot, my fingers and wrists would start getting fatigued quickly. My typing style also had
space for improvement, with my left hand stealing a lot of work from the right hand and my fingers
hitting the wrong keys. I was a touch typist, but following my own style that was hardly optimal.
All this got me looking for something different, an ergonomic keyboard.
After getting my Cherry finished, my brother messaged me
that his company was emptying
their old office and were throwing away some sort of IBM typerwiter. He asked if I would be interested
in taking it instead, to save it from going to the landfill. Of course I was, and so I was soon in
possession of a working IBM Wheelwriter 6747-2. The Wheelwriter is an electric typerwiter
introduced by IBM in 1984 to replace the earlier Selectric. It has a keyboard with similar
construction to that of the famous IBM Model M, using the same buckling spring mechanism. The unit
my brother saved for me is from 1986.
I myself had no use for a typewriter, but I was
very interested in its keyboard, that seemed to be in perfect condition. All the keys responded
properly, so it was just a matter of disconnecting the keyboard and converting it into USB usage. This
is how my conversion story started.
After quite some time in development, I’ve now deployed Mebe 2 on
this site, to replace the aging Mebe codebase. The earlier blog engine was written with Phoenix, which
while being a great framework, was a bit heavy handed for the engine’s minimal needs. Mebe 2 has the
old engine’s Markdown parsing and DB logic, but the web side is totally rewritten. The framework I
chose is Raxx, because it’s quite minimal but also mainly
because I just wanted to learn it. Alternatives are good.
The new blog engine has proper Distillery releases, so
keeping it running and making new fixes and features is a lot easier. It’s still in very early
development, though, as it’s missing tests and proper docs et cetera, but I figured I’d start
dogfooding it already, as this remake process has kept me from writing new posts. So hopefully in the
near future I’ll come out with some new stuff! See you till then!
I’ve always loved retro keyboards. Back at my previous job I used to
use a Keytronic keyboard
that I salvaged from the university’s trash room. I liked the 80’s/90’s beige aesthetic, the huge
keys, and the sound of typing on it. But it wasn’t a mechanical keyboard, just rubber dome. Once
I got to type on a mechanical keyboard, I knew I wanted one, but that meant I had to put my trusty
Keytronic to the side.
So about a month ago, I was very surprised and excited when I found an old looking keyboard in the
trash bin at my current employer.
I use OBS Studio to store replays of my games with my friends for later.
OBS writes two audio tracks to the file, one for game audio and one for my
mic. I was surprised to find that multi-track files were not properly supported
by many programs like Handbrake (or YouTube for that matter), so I needed to
combine the audio tracks.
When improving Code::Stats’s Atom plugin, I wanted to add the plugin version
as the User-Agent header: code-stats-atom/x.y.z. I used the fetch API and set the header there but it did nothing!
By googling a bit I found that User-Agent used to be a “dangerous” header that wasn’t allowed to be set in browsers.
It was only recently allowed, but Chromium
has not implemented support for it.
